Abstract. Effect of soil mulching and no-tillage cultivation system on emergence of plants and yield of scorzonera roots was investigated. Soil mulching with oats allowed to improve of plants emergence and to increase total and marketable yield of roots.

Summary
Field experiment was carried out at the Experimental Station of the Agricultural University of Lublin, on the gray brown podsolic soil in years 1997 and 1999. The experimental plant was scorzonera (Scorzonera hispanica L.) cultivar ‘Lange Jan’. The purpose of studies was determination of scorzonera yielding possibilities in differentiated soil and plants cultivation systems. In the experiment, the effect of soil mulching with white mustard, spring vetch, tansy phacelia, oats and no-tillage cultivation system on emergence and on the total and marketable yield of scorzonera roots was estimated.
Among investigated mulches the oats created the best conditions for emergence of plants and scorzonera yielding. The biggest total and marketable yield of roots was harvested from the objects with conventional soil cultivation system.
